The University of Colorado is a gun-free zone, with the exception of university police, and they have some tips for men or women who find themselves in the midst of a brutal attack.

According to the university’s Department of Public Safety, telling your attacker that you have a disease or are menstruating, or vomiting or urinating on yourself are all good ways to send your attacker running for the hills.

2. Your instinct may be to scream, go ahead! It may startle your attacker and give you an opportunity to run away.

3. Kick off your shoes if you have time and can’t run in them.

4. Don’t take time to look back; just get away.

5. If your life is in danger, passive resistance may be your best defense.

6. Tell your attacker that you have a disease or are menstruating.

7. Vomiting or urinating may also convince the attacker to leave you alone.

8. Yelling, hitting or biting may give you a chance to escape, do it!

9. Understand that some actions on your part might lead to more harm.

10. Remember, every emergency situation is different. Only you can decide which action is most appropriate

Any firearms are banned from the campus as well as many other makeshift items. “Dangerous or illegal weapons,” according to the Weapons Control subsection of the university’s policies, may include: “slingshots, cross-knuckles, knuckles of lead, brass or other metal, any bowie knife, dirk, dagger or similar knife, or any knife having the appearance of a pocket knife, the blade of which can be opened by a flick of a button, pressure on the handle or other mechanical contrivance.”
